METHOD FOR MANUFACTURING THREE-DIMENSIONAL BUILDING ELEMENTS BY 3D-PRINTING METHOD Russian patent published in 2023 - IPC E04G21/20 B33Y10/00 

FIELD: construction; 3D objects.

SUBSTANCE: invention relates to the field of manufacturing 3D objects using additive technology in the field of construction, in particular for the construction of enclosing structures using additive 3D printing technologies, and can be used to form products such as wood boards and bulk building parts. The technical result of the invention will expand the scope of 3D printing technologies for construction, improve the physical and mechanical properties, which will make it possible to obtain a material that is homogeneous in properties without the addition of adhesives or other substances when using additive technologies. The technical result is achieved by the fact that the method of manufacturing three-dimensional products of building elements by 3D printing includes the formation of layers from the raw mass by extrusion through a nozzle layer by layer, while hydrodynamically activated wood pulp is used as the raw material, which is squeezed out through the extruder nozzle layer by layer by the method of cold extrusion, while each underlying layer of hydrodynamically activated wood pulp is exposed to microwave radiation to redistribute moisture in it.

EFFECT: expansion of the scope of 3D printing technologies for construction, improvement of the physical and mechanical properties.
